Taking note of the equilibrium
4HCl(g) + O2(g) ----> 2H2(g) + 2Cl2(g).
What would be the the equilibrium law expression for the balanced chemical equation?
Remember that Keq = the product of the products of the reaction divided by the product of the reactants, each raised to a power indicated by the coefficient in the balance chemical equation.
My best answer would be:
HCl]4[O2] / [H2O]2[Cl2]2
Is this correct?
No. See my response to your repost above.
H2 and Cl2 are the products of the reaction. Right? and where did the H2O come from? That isn't anywhere in the equation.
